Analytics Reporting API v4 中的示例 HelloAnalytics.py 的问题

Question

official Quickstart Webpage 上的 Google 的 sample code 已过时且无法使用。

作为Google encourages to use StackOverflow，我不仅希望在以下问题上得到帮助，还希望激励 Google 更新他们的示例代码。

• 我 pip 安装了 google-api-python-client（没有 sudo，btw）。

• 不再有SERVICE_ACCOUNT_EMAIL (for years)。

• 作为KEY_FILE_LOCATION，我输入了 JSON 文件的名称。这就是您所说的“来自开发者控制台的适当值”吗？

• 我修复了第 65、68 和 70 行中的打印函数（这也是 confused others，特别是因为 Python 2.7 是 deprecated 用于 google-api-python-client）。

如果我运行它，我会收到以下错误：

Traceback (most recent call last):
  File "/Users/ralf/code/test_snippets/20-06-17_google_analytics_api/HelloAnalytics.py", line 4, in <module>
    from oauth2client.service_account import ServiceAccountCredentials
ModuleNotFoundError: No module named 'oauth2client'

很明显，缺少导入。 oauth2client 已弃用，他们推荐 google-auth 和 oauthlib。

我怎样才能让它工作？欢迎任何提示，请 Google 修复该示例代码，以免其他人进行令人沮丧和乏味的研究。

谢谢！

Google 现已更新示例代码（感谢DaImTo），如下所示：

"""Hello Analytics Reporting API V4."""

from apiclient.discovery import build
from oauth2client.service_account import ServiceAccountCredentials


SCOPES = ['https://www.googleapis.com/auth/analytics.readonly']
KEY_FILE_LOCATION = '<REPLACE_WITH_JSON_FILE>'
VIEW_ID = '<REPLACE_WITH_VIEW_ID>'


def initialize_analyticsreporting():
  """Initializes an Analytics Reporting API V4 service object.

  Returns:
    An authorized Analytics Reporting API V4 service object.
  """
  credentials = ServiceAccountCredentials.from_json_keyfile_name(
      KEY_FILE_LOCATION, SCOPES)

  # Build the service object.
  analytics = build('analyticsreporting', 'v4', credentials=credentials)

  return analytics


def get_report(analytics):
  """Queries the Analytics Reporting API V4.

  Args:
    analytics: An authorized Analytics Reporting API V4 service object.
  Returns:
    The Analytics Reporting API V4 response.
  """
  return analytics.reports().batchGet(
      body={
        'reportRequests': [
        {
          'viewId': VIEW_ID,
          'dateRanges': [{'startDate': '7daysAgo', 'endDate': 'today'}],
          'metrics': [{'expression': 'ga:sessions'}],
          'dimensions': [{'name': 'ga:country'}]
        }]
      }
  ).execute()


def print_response(response):
  """Parses and prints the Analytics Reporting API V4 response.

  Args:
    response: An Analytics Reporting API V4 response.
  """
  for report in response.get('reports', []):
    columnHeader = report.get('columnHeader', {})
    dimensionHeaders = columnHeader.get('dimensions', [])
    metricHeaders = columnHeader.get('metricHeader', {}).get('metricHeaderEntries', [])

    for row in report.get('data', {}).get('rows', []):
      dimensions = row.get('dimensions', [])
      dateRangeValues = row.get('metrics', [])

      for header, dimension in zip(dimensionHeaders, dimensions):
        print(header + ': ', dimension)

      for i, values in enumerate(dateRangeValues):
        print('Date range:', str(i))
        for metricHeader, value in zip(metricHeaders, values.get('values')):
          print(metricHeader.get('name') + ':', value)


def main():
  analytics = initialize_analyticsreporting()
  response = get_report(analytics)
  print_response(response)

if __name__ == '__main__':
  main()

不幸的是，我仍然收到错误：

Exception has occurred: HttpError
<HttpError 403 when requesting https://analyticsreporting.googleapis.com/v4/reports:batchGet?alt=json returned "User does not have sufficient permissions for this profile.">
  File "/Users/ralf/code/test_snippets/20-07-01_google_analytics_api/HelloAnalytics.py", line 42, in get_report
    'dimensions': [{'name': 'ga:country'}]
  File "/Users/ralf/code/test_snippets/20-07-01_google_analytics_api/HelloAnalytics.py", line 75, in main
    response = get_report(analytics)
  File "/Users/ralf/code/test_snippets/20-07-01_google_analytics_api/HelloAnalytics.py", line 80, in <module>
    main()

我仔细按照here 所述的步骤进行操作，尤其是Create Credentials 和Add service account to the Google Analytics account，但显然出了点问题。我稍后会再试一次。
